摘要：

1. Male weanling Long-Evans rats were randomly assigned to either copper-adequate (6.0 mg Cu/kg feed) or copper-deficient (< 1.0 mg Cu/kg feed) diets for a 5 week period. 2. Cardiac ATP levels and energy charges did not differ between the two groups. Levels of NAD and phosphocreatine as well as the sum of pyridine nucleotides were greater in copper-deficient rats compared with copper-adequate rats using HPLC analysis. 3. Mitochondrial respiratory control ratios and oxygen consumption rates from copper-deficient rat hearts were depressed, although ADP:O ratios were similar to copper-adequate rat hearts.
